' PRESERVATIVE Pusan.

SPECIFICATION forming part of Letters Patent No. 372.861, dated November 8. 1887. Application filed May 24, 1887. Serial No. 939,223. (No specimens.)

To all; whom it may colwern:

Be it known that we, JaMEs T. MORGAN, of Winsted, in the county of Litchfield-and? State of Connecticut, and HUBERT W. Mon GAN, of Meriden, in the county of New Haven and State of Connecticut, have invented a new and useful Improvement in Preservative Paper, of which the following is a full, clear, and

exact description.

The object of our invention is to improve thepreservative paper for which Letters Patent N 0. 223,814 were granted to J. C. Penning- .ton January 27, 1880. 1

The design of our invention is to provide a preserving-paper adapted for inclosing silverware and other metallic goods, to protect them against the action of sulphureted hydrogen and other gases injurions to polished metal, and which is also useful in preserving meats, fruits, eggs, &e.

In carrying out our invention we take one pound of borax, one pound of saLsoda, and of any non poisonous caustic alkali (such as caustic soda) eight pounds. We dissolve these ingredients in water and reducethe solution until it has adensity 0! 30 Baum'. We then take one part of -oxide of iron rendered neutral and three parts of oxide of tin' or'zinc, and boil the whole together, either with or 30 without has taken up and dissolved as much of the capable of holding 'in metallic oxide as it is. solution. We then reduce the solution with water until ithas a density of about 12 Ban m6,

pressure, until-the alkaline solution of gluten or analogous material. This solution we allow to stand until it becomes quite clear. It is then drawn off for use and placed in a vat.

The preservative paper isvprepared by first 0 passing it through the above-described solution, then through calendcring-rolls while still moist, thus closing the fibers of the paper and giving it .a finely-finished or calendered surface. -The caleudering also closes the pores of 5 the paper, so as to render it more impervious to gases.

Our improved preservative paper is adapted for preserving metals from tarnishing; for preserving all kinds of meat, fruit, eggs, vegetables, &c.;for carpet-lining for protection against vermin, and for hanging in the rooms The paper is also used in the manufacture of boxes, caskets, and cases for containing perishable articles.

, Having thus fully described our invention, 'we claim as-new and desire tosecure by Letters Patent- A solution for saturating preservative paper, consisting of the following ingredients,

combined in about the proportions named:

borax, sal-soda, 'caustic alkali, oxide of iron, oxide of tin, or its described equivalent, glu-' ten, and water snbstantially as specified.
